How does HTML work?

  • Similar function to Markdown, identifies how stuff should be displayed
  • HTML is based on tags <tagname>content</tagname>
    • Note the “/” on the ending tag
  • See a markdown to html example below

Markdown

# This is a title

HTML

<h1>This is a title</h1>

Attributes

  • Tags can have additional info in attributes
  • Attributes are in the following format below
<tagname attribute_name="attribute_value" another_attribute="another_value"></tagname>

Some useful tags to know that are similar to markdown

![describe image](link to image)

Link Tag - Markdown
